Joints and finishes in Sheet homes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Sheet, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Sheet is about 1 mile north-east of Petersfield, in Hampshire. Sheet gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Our area takes in 683 places across Hampshire, large and small. For nearby work, see our Portsmouth page (16 miles or so).
Our applicators cover all of GU32 and GU31 for new build mastic and the streets around it. If you need new build mastic at a property on Mill Lane, Village Street and Farnham Road or a nearby road, our applicators can take on the job. We also cover Petersfield (1 mile south-west), Steep (1 mile north-west), Steep Marsh (1 mile north-west), Stroud (2 miles west) and Oakshott (2 miles north-west). We also work in nearby towns such as Havant (11 miles south), Horndean (8 miles south-west), Alton (10 miles north), Waterlooville (10 miles south-west), Purbrook (11 miles south-west) and Bordon (7 miles north).
What’s near Sheet
Around Sheet, our work takes us to homes and buildings near The Queens Head pub, Churcher's College and The Petersfield School and the streets around them. Sheet’s nearest station is Petersfield station, about 1.1 miles south-west of the centre. Other landmarks nearby include Petersfield Community Hospital (1.3 miles south-west) and Bear Museum (1.1 miles south-west). Green spaces nearby include Liss Riverside Railway Walk South and Wheatham Hill.
How we handle new build mastic in Sheet
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include second-fix sealing on new plots and shower seals failing in the first year or two, on kitchens, windows & doors and plot handovers.
Older homes in small places like Sheet often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months.

How the job changes by surface
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep water off fresh sealant until it has cured
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
- Record problems with dated pictures
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
What we cannot put right
We will always be straight with you, so here’s what sealant cannot fix:
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
- Baths and trays that move too much for sealant to cope with
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Common questions in Sheet
Is Sheet within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Sheet for new build mastic?
Yes. We work across London and the South East, and Sheet is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Is there a guarantee?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish and agree it with you.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How much does new build mastic cost in Sheet?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Sheet, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- Clear items away from the joints we are working on

Related advice
Signs you need new build mastic in Sheet
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
People usually contact us when they notice something like this:
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
- Gaps between new skirting and floors
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Petersfield station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
